General Biology Additional InformationFucus spiralis spends up to 90 percent of the time out of the water. It can tolerate a high level of desiccation, being able to survive 70 to 80 percent water loss. Distinct varieties of Fucus spiralis have been recognised, such as Fucus spiralis forma nanus, which is a dwarf form present on exposed shores. Fucus spiralis also hybridises with Fucus vesiculosus providing considerable difficulty in identification.
